24 hours and you've not gotten a response? Odd. If I tell you something that is completely eroneous, then someone will pipe in and correct me I'll bet....

funny thing about this one, is your biggest question is a Coating Question, not really an oven question.

If you go to almost any website that sells powder, they have the powder listed and the curing paramaters right there with 'em. Most powders cure between 350-400 degrees.... Some a little higher, some a little lower.... Some really fast, some take a while longer. To sum up though, each powder has it's own curing parameters....

If you build your oven to go above 500, to maybe 550, outgassing parts will be much more effective, as you generally want to cook cast parts at 50 to 100 degrees above cure temp, for at least a double cure cycle time,.... as part of the preperation for coating. Billet and sheet metals do not need outgassing unless they are assemblies that cannot be un-assembled,... ie, welded or riveted.... This outgassing will cook off grease or bring it to the surface of the cast part or out of cracks and seams of assemblies.

A few considerations anyway....

Oh .... these are my opinions and I'm certainly not claiming to be the "be-all end-all" in this department.

Sounds good to me Scott.

[Grumple]

Sounds good to me too Scott.

sounds great scott. so outgassing is basically just cooking whatever i powdercoat before i powder coat, doing it around 40 degress higher then w/e the temp is supposed to be

is it bad to powder coat a hot piece of metal? or should it be cool? and, do i need to make smooth object porus with sand paper, for powder coating

advised, i bought a welder 2 days ago, my welds blow


I AM, buying 1/2 inch sheet metal, or 1/4 do insulate the inside, leaving a inch space less then what you see


am i going in the right direction? critisize, or however you spell it hehe

[whatrwedoingnow]

i will be doing supports and possibly a insulation layer


the right side will have a viewing window made from glass


welding sheet metal sucks! so far its just tacked together, ill be sealing it up soon


this morning i added the start of supports. my welds suck. they hold though im trying to get better, butt this sheet metal isnt the thickest
most deffinetly entertaining a insulation layer to retain some sort of heat

[whatrwedoingnow]

ugh i need sleep or something, im exausted no sleep sucks

fell asleep around noon. and woke up around 7, and did some more work

[whatrwedoingnow]

will be using the other door on the bottom if it fits, or ill extend the one on there

and the pole across is where ill be hanging ****
the welding is slowly getting easier


and the swivels. hold the door,so i say im doing a decent job



the parts with the poles, ill be welding thicker sheet metal, so it will retain heat, an leave 1 inch space between the sheetmtal, and the inside thicker sheet metal

Man, I'm amazed at the many ways people do this stuff! Not how I'd do it, but it may just work fine. The biggest problem I'm seeing in your build, is the amount of space you are allowing for insulation. Rule of thumb is, 1" if insulation for every 100 degrees of temp rise you expect. So If you are looking to raise the temp to 500-550, you'll need 4.5 - 5 inches of insulation. At the 550 range you can still get away with 4 inches of ins.... but there will be a price to pay in heat loss, and energy bills.

The gun set-up is a good start for a person to learn and coat a lot of schmancy stuff with.... There are many others to check out too, in the same range of price.
